摘要

模拟世界和数字世界之间的接口可能发生轻微的不规范(SOS)故障。如果分布式系统中的错误节点产生的输出信号(时间或值)稍微超出指定的窗口，则一些节点将正确接收到该信号，而另一些节点可能无法接收到该信号。这种情况将导致分布式系统的不一致状态。在TTP/C通信控制器执行软件实现的故障注入过程中，我们给出了在时间触发体系结构和总线互连结构中观察到的时序SOS故障。分析并提出了在时间触发体系结构中避免临时SOS故障发生的解决方案。

Slightly-off-specification failures in the time-triggered architecture

Slightly-off-specification (SOS) failures can occur at the interface between the analog and the digital world. If an erroneous node in a distributed system produces an output signal (in time or value) slightly outside the specified window, some nodes will correctly receive this signal, while others might fail to receive it. Such a scenario will result in an inconsistent state of the distributed system. We present the observed temporal SOS failures in the time-triggered architecture with the bus interconnection structure during the execution of the software implemented fault injection in the TTP/C communication controller. Solutions to avoid the occurrence of the temporal SOS failures in the time-triggered architecture are analyzed and presented.
